Bezzera Leaking Wand

Experiencing a leaking wand on your Bezzera machine?
This is a minor issue that naturally occurs over time due to regular wear and tear.

The solution applies to all Bezzera espresso machines equipped with a joystick steam or hot water wand, and may also be suitable for similar models from other brands.

Specifically, it is compatible with the following Bezzera models:
BZ07, BZ09, BZ10, BZ13, Crema, Unica, Magica, Mitica, Duo, Matrix, and Strega.

WHY DOES IT HAPPEN?

The steam and hot water wands operate by sealing gaskets that control the release and retention of pressure. When you twist the knobs, the valve is pressed open or closed.

Over time, these gaskets—though made from high-grade, food-safe silicone—can harden, deform, and eventually require replacement. Another contributing factor can be the loss of lubrication, which normally ensures smooth rotation of the wand. Limescale buildup may also develop around the sealing surfaces, preventing the gaskets from forming a proper seal. In some cases, parts may further loosen due to mishandling.

Howver, the most common cause of leaks, however, comes when the user turn the joystick wands in their locked position too much, this may cause an unexpected tightening and additional compression to the activation button.

In short, leakage is typically the result of natural wear and tear. This is a universal issue across all espresso machine brands, much like how brake pads in cars need periodic replacement.

WHEN DOES IT HAPPEN?

It is difficult to predict exactly when leaks will occur, but they often begin as small drips. In many cases, these can be resolved without the need for replacement parts.

A common habit among users is to rotate the wands excessively in their locked position. This is unnecessary and may result in over-tightening of the knob, which places constant pressure on the activation button and cause the valve to remain open causing leaks.

Bezzera Leaking Wand Problem 1 – Leaking continuously from the wand tips

WARNING: BECAREFUL OF HOT SURFACE

This is a minor issue that can sometimes occur if the machine was lifted or handled by the wand during unpacking, causing the wand cap to be slightly overtightened. It may also result from excessive knob rotation when locking the wand, which places additional pressure on the mechanism.

The solution is demonstrated in the video above.
The parts list provided below applies to the water wand, and the same method is also effective for the steam wand.

For BZ07, BZ09, BZ10, BZ13 and Crema

The leakage occurs because the cap (Part 2) is overtightened, which presses against the button (Part 4) and prevents the valve from closing properly. This usually happens when the knob (Parts 1 and 3) is rotated excessively, causing the cap (Part 2) to screw in tighter than intended.

Solution

For models such as the Crema or BZ13, you may need to remove the top panel to access the locking nut (Part 8). This can be done by removing the two screws with a 3mm Allen key.

1. Loosen the cap (Part 2):
   Gently loosen the cap by turning it counterclockwise. This should immediately stop the leak. (Turn clockwise to tighten if required.)
   
2. Adjust the locking nut (Part 8) if necessary:
   If the cap is too tight, loosen the locking nut using a size 22 wrench or an adjustable wrench. Turn the nut clockwise to loosen and counterclockwise to tighten.
   – For BZ13 and Crema models, the locking nut is located inside the grouphead compartment. You will need to remove the top panel, as shown in the illustration above, to access it.
   
3. Retighten carefully – IMPORTANT:
   Once the adjustment is complete, slightly tighten the locking nut (Part 8) if required. Take care not to overtighten, as this may twist the entire wand (Part 12) out of alignment.

For Magica, Mitica and Strega

The leakage occurs because the cap (Part 2) is overtightened, which presses against the button (Part 4) and prevents the valve from closing properly. This usually happens when the knob (Parts 1 and 3) is rotated excessively, causing the cap (Part 2) to screw in tighter than intended.

Solution

1. Loosen the cap (Part 2):
   Gently loosen the cap by turning it counterclockwise. This should immediately stop the leak. (Turn clockwise to tighten if required.)
   
2. Adjust the locking nut (Part 8) if necessary:
   If the cap is too tight, loosen the locking nut using a size 22 wrench or an adjustable wrench. Turn the nut clockwise to loosen and counterclockwise to tighten.
   
3. Retighten carefully – IMPORTANT:
   Once the adjustment is complete, slightly tighten the locking nut (Part 8) if required. Take care not to overtighten, as this may twist the entire wand (Part 63) out of alignment.

The above should work for most of the cases. If that doesn’t work, it means that the gaskets are clogged with limescale. You will need to replace part 7, 10 and 58 for BZ line, or part 12, 60 and 64 for Magica/Mitica/Strega.

The same can happen to the steam wand, then you will need to buy the appropriate kits from Steam wand service kit

You can also send for maintenance, and we will refurbish the internal components in the wands.

Bezzera Leaking Wand Problem 2 – Leaking from around the nut

Refer to the photo above.

If Point A is leaking, a slight tightening may resolve the issue. First, use your fingers to tighten it as much as possible, then use a spanner to turn it an additional quarter round. Be careful not to overtighten, as this can damage the gasket. If you do not have a spanner, wrapping the nut with a rubber band can provide extra grip for hand tightening.

If tightening resolves the leak, we recommend applying a small amount of food-grade grease around the ball joint, accessible from the underside of Point B. This quick fix helps the joint move smoothly and may extend the lifespan of the seal before the issue recurs. Food-grade grease can be purchased from the links provided below.

Food Grade Grease(Original) or Food Grade Grease(Compatible).

If tightening doesn’t help with that, then you will need to buy steam wand service kit or water wand kit and replace the gaskets or send for servicing

If Point B or Point C is leaking:

You will need to buy steam wand service kit or water wand kit and replace the gaskets or send for servicing

CONCLUSION

Leaking wands are a common occurrence over time, as gaskets naturally wear out and require replacement. They are designed to be serviceable for this very reason. In most cases, however, leaks are not due to gasket failure but rather from excessive twisting or rotating of the wands, which can lead to fittings becoming either too loose or overtightened.
